Dual screen on ATI - SOLARIS x86 ?

[Kalle Anka]

 am using Solaris 10 x86 on a Dell Latitude D600
laptop, with ATI mobility 9000 radeon. I have juggled
with the xorg.conf and got dual screen working
sometimes. Other times, it doesnt work. Quite
randomly. The screen on the laptop shows strange
colors, while the external TFT screen works. Anyone
spots the error in my xorg.conf file?

Besides, is it possible to use dual screen with
different resolutions? My laptop running 1400x1050 and
the external 1680x1050? Or must both have identical
resolutions?
